Geology
1. Irregular and lensing lodes and veins of argentiferous lead mineralizations with varying zinc, copper, and minor gold along fault fissures and in breccia zones in Jurassic - Triassic, Cretaceous and Laramide andesitic and rhyolitic volcanics, probably intruded below a Laramide granitic body. Some replacement of interbedded linestone in volcanics. Silver enrichment near the surface.
2. Disseminations and fissure fillings of copper mineralization, with varying lead and zince, in brecciated zones of Cretaceous andesite.
3. Irregular mantos, lenses, and pods of manganese - silver ore as replacements in silicified, altered, and brecciated Paleozoic limestone and Jurassic - Triassic volcanics and agglomerate.
4. Small, spotty, and generally low grade gold placer deposits.5.
Types of operation and production
Shaft, tunnel, adit, and open pit operations. Developed and mined from about the 1850's to the middle 1960's. Total production would be some 1.5 million tons of ore containing about 86,000 tons of zinc, 72,000 tons of lead, 9.2 million ounces of silver, 3,100 tons of copper and 4,300 ounces of gold. An estimated 10,000 long tons of manganese ore of variable grade also was produced, much of it as an argentiferous smelter flux. Placer gold output is unknown but probably minor5.
